FOD2742CR2

Overview

The onsemi FOD2742CR2 is a single-channel optically isolated amplifier featuring an error amplifier and NPN phototransistor output. It provides 2500 Vrms insulation voltage with a 1.5 V forward voltage. The device operates within a temperature range of -25°C to +85°C in an SOIC-8 package. Key electrical parameters include a 100% current transfer ratio, 50 mA maximum collector current, 70 V maximum collector-emitter voltage, and 400 mV saturation voltage. Power dissipation is rated at 145 mW, supported by a 2.495 V reference voltage.

Feature Summary

Integrates an error amplifier for precision signal isolation
Provides high-voltage galvanic isolation between input and output circuits
Utilizes NPN phototransistor output for digital or analog switching applications

Applications

High-voltage isolation interfaces
Error amplifier circuits requiring optical feedback
Industrial control systems needing signal separation

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm the specific suffix 'CR2' matches required packaging and tape-and-reel specifications. Check for end-of-life status or obsolescence notices from onsemi before finalizing design-in decisions. Ensure compliance with RoHS directives if applicable to the target market regulations.

Selection Notes

Select this component when 2500 Vrms isolation is required alongside integrated error amplification. Compare against standard optocouplers if external compensation networks are undesirable. Consider the SOIC-8 footprint constraints and thermal dissipation limits of 145 mW during PCB layout planning.

Part Context

This part belongs to the FOD2742B series of optically isolated amplifiers. It shares functional similarities with other models in the family but differs in packaging and specific electrical tolerances. The series targets applications demanding reliable signal transmission across high-potential barriers.
